A girl (teenaged or older) who is basically still tied to her father's apron-strings (or whatever the male equivolent of apron-springs are). She is usually a spoilt brat, owns nice clothes, maybe a car, has her hair done every five minutes, all on Daddy's credit card. Dates boys she thinks are good enough for the likes of her, but if they do anything wrong then Daddy will basically be after giving them a stern talking-to (or a good hiding, depending on what sort of person Daddy is).

"There's that Daddy's Little Girl again. She just pulled up in her brand new car and has strutted in wearing designer clothes and with her expensive hair-do. Do you think she ever wonders what it's like to earn anything in life?"

(noun)
a.k.a. Daddy's Girl
Belittling and insulting term for a female who "won't do anything her daddy told her not to", so to speak. Often used for younger girls who don't drink alcohol, don't smoke, don't take other drugs, go to church every Sunday, don't engage in pre-marital sex, do their homework every day, go to bed early, never disappoint their parents, and/or similar situations.
Can also be used on older women with simlar personality treats.
